In the accompanying drawin s, there is shown aC window casing-A of orinary construction which includesv 'the usual sides 5-5a, a top 6, and a sill 7. 1

The awning is composed of a lurality of metal sections a, b, c, d, and e, t e section a being the lowermost section when the awning 1s in its operative or extended position, and the section e being the upper section, whereas the sections b, c, and d are intermediate sections. These sectionsl are' preferably A60 stamped from sheet metal, and all have a similar form. Each section includes spaced sides 8-8 which are substantially triangular- 1n shape and a top 9 which is preferably rectangular in shape. The top section e is rlgidly attached to the window casing A and the forward edge of the section is provided with a down-turned lip 10. The next lower section d is provided with an u standing lip 11 along its inner edge which 1s adapted to 70 engage the lip 10 and thereby limit the outward movement of said section d. This section d is pivotally connected as at 12 to the sides of the section e. The top v9 of the sect1on c is provided along its forward edge 75 with a down-turned lip 13 and alon itsrear edge with an up-turned lig 14, t e latter being-engageable with the wn-turned lip 15' extending along the forward edge of the section d. The section e is ivoted as at 16V 80 The section b is formed along the front edge of the to 9 with a downwardly extending lip 17 and alon its rear edge with an upwardly extending 'p 18, the atter being adapted to en- 85 gage the downwardly extending lip 13 of the section c. The section b is p1votally connected as at 18a to the section d. The top 9 of the lowermo'st section a is provided along its rear edge with a forwardly extend- .ing

ing lip 19 which is adapted to engage the lip 17 of the section b. The section a is pivoted as at 20 to the section d. The lowermost section a is also provided with a downwardly projecting flange which extends along the sides of the section as at 21-21 an along its front as at 22. The pivots 12, 16, 18a, and 20 are disposed in a vertical line one above 4the other so as to permit the awnsections to be readily telescoped when moved upwardly to their inoperative positions, or to permit the sections to be readily extended to their operative positions. When thus extended the sections are held in their operative positions by means of the interengaging lips.

The above construction is substantially identical with that shown in the Cloud and Bitterman Patent 1,615,214 referred to above.

In order to positively raise and lower the awning sections, we have provided a manually operable mechanism which includes a vertically movable element mounted on the window casing, a combined pull and push link which is pivotally connected to the element and to the lowermost awning sections, and a means for imparting vertical movements to the element inV order to raise and lower the sections. For this purpose we have provided an endless band B which is trained around a sprocket wheel 23 journaled on a shaft 24 which is fixed in a casing 25 secured to the outer face of the side 5 of the window casing and adjacent the sill 7. This endless band B extends upwardly from the sprocket wheel 23 in parallelism with the adjacent side 5 of the window casing, and is then trained over a pair of pulleys 26 and 27 mounted in a supporting frame 28, the latter being fixed t0 the top 6 of the window casing. The supportingr frame 28 is located directly above the sprocket wheel 23. The endlessA band B then extends horizontally along the top 6 of the window casing and thence over pulleys 29 and 30 which are secured to a supporting frame 31 fixed to the top 6 of the window casing adjacent the other side 5a thereof. The bight portion 32 of the endless band B thence extends downwardly along the adj acentside 5a of the window casing and is trained around a pulley 33 which is journaled on a supporting frame 34 fixed to the side face of the side 5a of the window casing. The endless band B is formed of two sections, one consisting of a length of wire 35 or other flexible means, and the other consisting of a sprocket chain 36. The wire connection 35 extends around the pulleys 26, 27,29, 30, and 33, whereas the sprocket chain 36 extends around the sprocket wheel 23. Interposed in the wire connection v35 are connector elements 37, and carried by each elementl is an axle 38 on which is journaled a guide roller 39. Also journaled on each axle 38 is a combined pull and push link 40, the other end ofthe link being pivotally connected as atv 41 to the flange 21 of the lower awning section a. The, guide rollers 39 cooperate with vertically disposed guides 42 which are secured to the sides of the window casing.

Thus it will be seen that the endless band B is not only movable around fixed points,` but one stretch of the band is movable vertically and carries the connector element 37 therewith. It will also be observed that, by means of the guides 42 and the cooperating guide rollers 39, the elements 37 will be guided-in straight vertical lines and will be retained against bodily movements inwardly or outwardly relative to the window casing. Consequently,-when the endless' band B is 'moved, the connector elements 37 will be moved vertically and will carry with them in'- ner pivotal ends of the combined push and pull links 40. Thus, when the connector elements 37 are moved upwardly the links 40 will positively swing the awning sections upwardly from an operative extended position to an inoperative closed position, the connector elements 37 are moved downwardly, the links will function to positively swing the awning. sections downwardly and outwardly to their operative extended position.

In order to move the endless band B and thereby either raise or lower the awning, we have provided an operating shaft 43 and have journaled the same in the window casing. Fixed to the outer end of the shaft 43 is a gear 44 which meshes with a gear 45 fixed to the sprocket wheel shaft 24. The shaft 43 extends into the housing 25 and both gears 44 and 45 are enclosed within said housing. A crank handle 46 is fixed tothe inner end of the operating shaft 43 and consequently, by rotating the handle, the endless band B will be moved and the awning raised or lowered, as above described.

The pulley 33 is journaled on a frame 33a which is vertically adjustable along the guide 42 by means of a screw 335 whereby the tension of the endless band may be varied.

It will be observed that both connector elements 37 and both links 40 are moved in unison, either upwardly or downwardly.

In the modified form shown in Figures 12 to- 16 inclusive, I have mounted on the sides 5 of the window casing vertically disposed housings 47 and 48 respectively. Journaled in brackets 49-49 secured to the top 6 of the window casing is a shaft 50 having its ends projecting into the casings 47 and 48. Fixed to the ends of the shaft 50 and located within said housings are sprocket wheels 51 and 52 respectively. A sprocket chain 53 is trained around the sprocket wheel 51 and extends downwardly through openings 54.-54 formed in the lower end of the casing 47, and the lower end of the sprocket chain is trained and, when around a sprocket wheel 55 which is fixed to a shaft 56 journaled in a casino` 57 secured to the front face of the window casing. Trained around the sprocket wheel 52 1s a sprocket chain 58, and this chain' extends' of guide rollers 62--62 which cooperate with a vertically disposed guide 63 mounted in the associated hdusing 47, or 48 as the case'may be. Each of the housings-47 and 48 1s U- shaped in cross section and is closed .by a cover 64 which isformed with a vertlcally disposed slot 65 along which the axle 61 moves when the awning sections are moved upwardly or downwardly.

In order to exert elther a positive upward pull on links 40 or a downward thrust thereon, we have provided an operating shaft 66 which is journaled in the window casing. Flxed to one end of the shaft 66 is a bevel ear 67 which meshes with a bevel gear 68 xed on the shaft 56. A crank handle 69 is fixed to the inner end of the shaft 66, and consequently, when the shaft is rotated, both sprocket chains .53 and 58, together with the connecting cross shaft 50, will be operated. Consequently both elements 60 will be simultaneously raised or lowered and therefore both links 40 will be correspondingly moved.

In view of the above it will be apparent that we have provided a lurality of telescoping awning sections w ich are mounted to swing upwardly from an operative extended position to an inoperative closed position and vice versa. We have provided means for raising the sections, and `this means includes a vertically movable element, a combined pull and push link which is pivotally connected to the element and to the lowermost awning section, and have provided means 4for imparting vertical movements to the element whereby a positive upward pull will be imparted to the link 40 or whereby a positive downward thrust will be imparted to the llink so as to raise or lower the awning sections.
